    09 Ultra 260 wont rev past 7000 rpm

    I bought a damaged Ultra 260 which would not rev past 7000 rpm which was recently overhauled. I found water in the oil and my mechanic found it had a cracked head. I had the head replaced and the oil is clean yet the craft still wont run past 7000 rpm shows 58 - 60 on Speedo. Boost reference is showing full and crafts starts, idle and accelerates smooth.

    Compression is good.

    I second the belt. I had my motor rebuilt and after 2 yrs arguing with the shop I starting looking for myself and found the belt needed to be replaced. Before belt 7000 rpms. After I hit 8200. Man did I miss the power
